Use the tag in GitLab webhook in jenkins build

Question

I have a webhook in GitLab to trigger a Jenkins job when ever a new tag is created. Is there a way to use the new tag that triggered the Jenkins job in the Jenkins job? For example, lets say I pushed the tag v.1.5 to my repo.

git tag -a v1.5 -m "version 1.5"
git push --tags

Now, I want to use the tag v.1.5 in the shell execution in the Jenkins build (Execute shell).

echo <tag that triggered this job>

Is there a way to read and use the tag from the POST request?

Answer 1

You can read the tag from the local repo using git describe .

tag=$(git describe --tags)
echo "tag = "$tag
